' 5 Claims. (01. 2041),

This invention relates to a device for securing a removable head to abarrel. v One of the objects of the in'vention is-to provide a deviceofthis character which isso-constituted and organized that it maybe conveniently applied and releasedand yet is of simplegddrable andcompactconstruction; In carrying out "the present invention; an=op-'- expandingthe ringand has combined therewith the crank handle in such a novelmanner. that the handle may be conveniently used after the manner ofahigh speed wrench to cause the screw to contractor expand the ring;When not in use the handle may be compactly foldedagainst tain novelfeatures of the construction, arrangement and combination of parts whichwill be hereinafter more fully described and particu- I larly pointedout in the appended claims, reference being had to the accompanyingdrawing,

forming a part of this specification, and in which;

Figure 1 is a view in top plan showing a head equipped with a closuredevice embodying the 7 present invention; and."

tween the flange structure 4 and the rolled bead 2.

The head is fastened in position to close and hermetically seal the openend of the barrel by means of a split clamping ring 6. This ring isconstructed of resilient sheet metal of ap--' I propriate gauge and itis of channel orconcave form sothat when it is'applied its upper portion1 bears downon the flange structure 4 of the head and its lower portion8 engages under therolled bead 2. U I

Adjacent its ends the ring 6 is provided with inwardly extendingapertured lugs 9 and I0 which in the upper wall thereof.

overlie the cupped portion of the head 3. An operating screw II isprovided and has the threaded portion of its shank interengagedwithinternal threads provided in the lug 9. The screw also has a smoothportion of its shankextending through a smooth opening provided thereforin the lug 10. This screw is constrained against axial movement relativeto the lug 9 by means of a collar l2'fixed thereto and engaging one sideof the lug In and its head 13 which is also" fixed to the shank andengages the other side In other words, the screw is of the lug l0.threadedly connected with the lug 9 and is swiveled to the lug I0.

Anoperating handle I5 is provided and is in the form of a crank having asuitable hand grip l6 at one end and having its other end permanentlyconnected by a universal joint designated at I! to the head of the screwH. The universal joint l1 comprises a part l8 secured to one end of thecrank handle and straddling and pivotally connected as at IE to a secondpart 20 which, in turn, is pivotally connected to'the bifurcated head l3of the screw II. The pivotal connection between the part 20 and the headI3 is at right angles to the pivot I9.

For the purpose of releasably securing the a handle 15 in position closeup against and parallel to the head 3 during shipment and storage, akeeper 25 is integrally formed or rigidly secured to an intermediateportion of the ring 6. This keeper presents an inwardly and horizontallyopening socket andis so positioned that this socket receives the curvedportion I6 of the handle l5. The handle I5 is releasably-retained in thekeeper 25 by means of a suitable pin 26 whichhas its head 21 resting onthe lower wall of the keep- 7 er and its shank extending-up through anopening from the keeper the portion of the pin 26 which projects abovethe keeper must be grasped and To release the handle Q the pin pulledupwardly until its head is received in the counter-sink 28 providedtherefor in the upper wall of the keeper at which time the crank handlemay be swung out of the keeper and then 5 raised to a position where itmay be conveniently operated to tighten up or release the screw.

While I have shown and described one conious'changes in the size, shapeand arrangement of the parts may be made without departing from thespirit of the invention or the scope of the subjoined claims.

The invention claimed is:

1. A device for securing a removable head to a barrel comprising a splitclamping ring, lugs secured to end portions of the ring and projectinginwardly over the barrel, an operating screw swiveled to one of the lugsand threadedly interconnected with the other, a crank handle, and auniversal joint permanently connecting one end of the crank handle tothe screw.

2. A device for securing a removable head to a barrel comprising a splitclamping ring, lugs secured to end portions of the ring and projectinginwardly over the barrel, an operating screw swiveled to one of the lugsand threadedly interconnected with the other, a crank handle, auniversal joint permanently connecting one end of the crank handle tothe screw, said crank handle being foldable to a position parallel tothe head when not in use, and a keeper engageable with the crank handleto hold it in folded position.

3. A device for securing a removable head to a barrel comprising a splitclamping ring, lugs secured to end portions of the ring and projectinginwardly over the barrel, an operating screw swiveled to one of the lugsand threadedly interconnected with the other, a crank handle, auniversal joint permanently connecting one end of the crank handle tothe screw, said crank handle being foldable to a position parallel tothe head when not in use, a keeper engageable with the crank handle tohold it in folded position, said keeper presenting an inwardly openingsocket and being positioned to engage a curved portion of the crankhandle, and releasable means for retaining the crank handle in thekeeper.

4. A device for securing a removable head to a barrel comprising a splitclamping ring, screw means cooperable with end portions of the ring forexpanding and contracting the same and a crank handle having a universalconnection with the screw means and manipulated to operate the 7 same,said crank handle also being foldable to a position within the confinesof the barrel, and means forreleasably retaining the handle in itsfolded position. l

, 5. A device for securing a removable head to a barrel comprising asplit clamping ring, a screw interconnected with the end portions of thering and operable whenturned to expand and. contract the ring dependingupon the direction in which the screw is turned, an operating handle,and a universal joint between the handle and one end of the screw topositively and permanently interconnect the handle and screw, and alsoto provide for folding of the handle to an inoperative, position withinthe confines of the barrel.
